tests: verify MSYS2 runtime deployments

We are about to change for which architectures the two separate MSYS2
runtime packages are built: the v3.3.* legacy package will be built only
for i686, the regular package only for x86_64.

To ensure that those changes are done correctly, let's document the
current behavior first.
